FLOOD OF THE TISZA RIVER IN 1932. By: GYÖRGY POGONYI. The flood of the Tisza River in 1932 attained a height surpassing all previous records.

The snow had fallen upon a well frozen soil, forming a thick layer on it, and the flood was caused by a sudden melting of this mass of snow beginning on March 4. Though at that time the Tisza and its tributaries were low and covered with ice, yet the thaw was so rapid that the ice floated down fairly easily and caused no trouble.
